Exhaust temperature of CFM56 engines range (Nozzle downstream temp)?

The CFM56 engine series, commonly used in aircraft like the Boeing 737, doesn't typically provide a specific temperature for the exhaust nozzle. The main temperature reference is the Exhaust Gas ...

How do after-burners work on jet planes?

The hot, fast-moving exhaust from a turbojet contains lots of excess oxygen with which more fuel could be burned, if you wanted to. And with no turbine wheel(s) immersed in that superhot exhaust (...

Why do new jet engines cost billions to design?

This is a great question! You hear this kind of question a lot on different subjects. the closer you look, the more you see the answer. There are some great comments here already, so I'll just add a ...

Function of the compressor in a gas turbine engine

Would a jet engine need the compressor? All heat engines require a compression step, only in turbomachinery the part involved is called compressor. But other engines also compress a medium as part of ...

Function of the compressor in a gas turbine engine

I think that both a practical and a thermodynamic answer can be given. As far as I understand it, the reasons are twofold. Correct From a practical point of view, compressing the air before the ...

Function of the compressor in a gas turbine engine

In order for a jet to create thrust, pressure must be created so the difference in pressure from the inside of the engine to the outside air will create a flow of a certain mass at a certain velocity. ...

Function of the compressor in a gas turbine engine

You don't. A (sc)ramjet doesn't have a compressor, as the forward velocity of the jet provides the necessary pressure. Most thermal engines do work by expanding a gas. In many cases, this gas expands ...

Function of the compressor in a gas turbine engine

The reason is thermodynamics: without the compressor, the power output of a gas turbine would be exactly zero. It's not about being "more efficient" but about fundamentally being able to ...

Function of the compressor in a gas turbine engine

The compressor raises the pressure and temperature at which the fuel is burned, thereby increasing the thermodynamic efficiency of the cycle (Brayton) on which the jet operates. Second, without the ...

Why are these characteristics of the FT-180 highlighted?

All aluminium and steel design: no plastic parts are present on the engine except for the carbon fiber inlet cowl. ===> Why is this important no to have plastic part? I thought that plastic was a ...
